PAVING.

SPECIFICATION forming part of Letters Patent No. 744,541, dated November 17, 1903.

Application filed May 28, 1903.

l To all whom t may concern.-

' for use in stalls, for sidewalks and streets, duc.

rial.

The invention consists in providing a paving of ordinary asphalt arranged upon coiled springs the lower ends ofwhich are held securely within cement or other suitable mate- An elastic material is arranged within each of the springs,and sand is'preferably packed about the springs, so as to form a substantially solid support for the asphalt.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a vertical section through paving constructed in accordance with my invention, and Fig. 2 is a horizontal section therethrough.

Referring to the igures by numerals of reference, 1 1 are coiled springs the lower ends of which` are embedded in cement 2 or other suitable material adapted to hold them firmly in upright positions. The springs are arranged close together, and each is filled with rubber 3, which bears upon the bed 2 and extends upward to the upper ends of the springs.

Serial Nol159,202. (No model.)

Sand is placed between the springs and together with said springs forms a bed upon which asphalt or other surface material 4 is placed. lWhen extreme pressure is brought to bear upon the asphalt, the springs 1 will be compressed, as is obvious, and the sand between the springs will be pressed inward against the rubber 3. It will be seen that this paving is extremely simple in construction, and as it is slightly resilient it is especially adapted for stalls in' stables and for various other purposes.

In the foregoing description I have shown the preferred form of my'inventiongbutI do not limit myself thereto, as I am aware that modiiications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as. new is--f 1. The combination with a bed having springs extending therefrom; of sur-face material mounted upon the springs, and granular material interposed between the springs. 2. The combination with a bed, and springs fixed therein and extending therefrom; of elastic material within the springs, granular material interposed between the springs, and surface material supportedb'y the springs.

In testimony whereof I affix my signature in presence of two'witnesses.
